Global warming is very common now a days.Global warming defines as the average temperature of the Earth’s atmosphere is gradually increasing, It thought the rises of temperature of the Earth will change permanently the Earth’s climate.
The debate is going on among peoples and electronic and printed media that this global warming is real or its just a theory but the scientist that working on climates are looking at the facts and data. They are all agreed that the planet Earth is warming. Scientist all are agreed that the average temperature of the near surface planet Earth rises between 0.4 and 0.8 °C over the last century and its temperature is increases more rapidly than previously record. . Intergovernmental Panel on Climate Change (IPCC) scientists predicted that the average temperature of the Earth would be increases between 1.4 and 5.8 °C by the next century. The year 2016 is annouced to be the hotest year ever sine Earth exists.
The primary cause for the Global warming over the last century is the increased Volume of greenhouse gases and carban dioxide which are mainly released by the burning of garbage, land cleaning, also the burning of fossil fuels,agriculture and activites of human. The presence carbon dioxide (CO2) in the atmosphere it acts as the covering or blanket by which heat is trapped and cause the warming of the planet. Due to all Global warming many changes will occur on planet Earthwhich includes the rising of sea levels due to the melting of glaciers and ice caps. It may also cause the severe weather events and storms.
How Global warming is affecting Pakistan
Pakistan contribution to climate chnage is very tiny. The greenhouse gas emissions is less than 1%. Pakistan is among the lowest in world who effects climate change. The emmision of greenhouse gases in pakistan largest source is energy sector its nearly about 51% and agriculture sector is 39%. 6% is by industrail processes, land use, land use change and forestry (LULUCF) 3% and waste emission of green house gases is 1%.
The some effects of global warming on pakistan is very severe and dangerous.
- Glaciers in the himalayas melts will be a biggest theart. Volumetric flow rate of the river increases to dangerous level. It will impact millions of lives. It cause Intense flood.
- One of the big therat to costal area dua to rise of sea level.
- The change in weather which cause increase in the intensity of severe weather condition.
- Water stressed condition which cause the reduction of agriculture productivity.
Health risks increased.
By reducing the amount of carbon dioxide (CO2) and heat trapping emissions in the atmosphere. We should stop the deforestation and increases the amount of trees and plants on planet Earth. The Higher Authorities should take some comprehensive action to support and implement the climate solutions.
